IMPROVED TIRE-SHRINKER.

TO'ALL WIIOM I'l MAY CONCERN:

'Be it 'known that I, EDWARD B. DECKER, of Bedford, in the county of Pike, and State ofIllinois, have invented a. new and improved '.lire-Shrinker;` and-I do hereby declare that the following is a full, clear, and exact descriptionthereof,,which will enable those skilled in the.art to make and use the same, reference being had to the accompanying drawing, Aand to the letters of reference marked thereon, forming part of this specification. l l

The gure is a perspective view of my improved tre-shrinker, opened to receive thetire.

My invention has for its object to furnish an improved machine for shrinking tire, vwhich shall be simple 'in construction, convenient to be used, and powerful in operation; and it consists in the-combination of the operating-lever, pivting-straps, and pivoted bars or levers, having clamps with stationary and-eccentric movable.

jaws attached to them for grasping the tire, the whole being constructed and arranged as hereinafter more fully described.

A and B are two bars or levers, p'ivoted to each other at one end, as shown in the dran'ing. AC is a."barid or strap, the ends of which are pivoted to the opposite sides of the end of the lever or barA, and which passes around the bar or lever B, which is made a little longer than the lcver A. D is the operating-lever or handle, -the end of which is pivotcd to thestrap C near the end of the lever A. E are straps, one end of which is pivoted to the opposite sides of the end of the lever B, and their other ends are pivoted to the opposite sides Vof the operating-lover or handle D, \at a little distance from the strap C. By this arrangement, .the ends of the levers A B are drawn together with great power, or forced apart by operating the lever or handle D. F and G- are the stationary jaws of the clamps, which are rmly attached to the levers or bars A B, and the forward ends of which are corrugated, or have teeth formed upon them, to enable them to take a rmerhold of the tire. H andvI are the movable jaws of the clamps, the forward ends or faces of which are corrugated, or

have teeth formed upon them, to enable them to take a firmer hold upon the tire. The jaws H and I are pivoted to thc levers A B, and their faces are made eccentric or cam-shaped, so that they may grasp the tircand hold -it rmly, whether it be thick or thin. The jaws H and I may be moved back and forth to grasp and release the tire by lever-handles formed upon or attached to their rear sides, or by cross-heads or haudlesfattached to their upper sides. Y

' Having thus described my invention, I claim as nc\v,1and desire to secure byLetters Patent- The combination of the operating-lever or handle D, pivotingstraps C and'E, pivted levers or bars A and B, having clamps with stationary jaws F G, and pivoted eccentvicjaws H I attached to the1n, with each other, substantially as herein shown'and described, and for the purpose set forth. I
